Path signals are not always what you want. This can be used to construct balancers and other helpful constructs. ago Yes, you can build your whole network with path signals, but: Path signals require more processing power than block signals large networks on a not-so-modern CPU will see the game's performance suffer. Block Signals: These separate track parts into 'blocks', which can contain only a single train per block. For instance, entry/exit signals will cause trains to take longer routes if a path is blocked, while path signals may wait. 1 Answer Sorted by: 54 There are six different types of signals you can use, and can be used as two-way signals for tracks meant to go both ways, or one-way signals for tracks meant to go in only a single direction. Path signals also can behave similar to entry/exit signals, although entry/exit signals have uses that path can't fully achieve. I use path signals for forks that have 4 or more tracks, as this is where they start to benefit. This is a major advantage against standard OpenTTD signals, where you had to place signals before and after junctions, which caused trains to block junctions while waiting.įor straight track and basic merges/splits, I stick to normal one-way signals. When both signals are replaced with One-way path signals, the station runs a lot smoother. It is not safe for a a train to wait at a signal immediately after a junction before the whole train has cleared the junction, as it would be blocking the junction while waiting, as illustrated in the example below. The first two signals selected are One-way path signals that uses to be Block Pre-entry signals and the next 3 Combo-signals are also causing trains to wait for the whole three blocks to be free. This is because it is only safe for a train to wait in front of a junction. The back of a Path signal is not considered a safe waiting position, and therefore paths are reserved through these signals.īecause the front of every signal is defined as a safe waiting position, you would normally not want to place a signal immediately behind a junction, only in front of a junction. Safe waiting positions are - by definition - in front of signals, depots and track ends. The Path signals are red by default, and will only show green as soon as a train can reserve a path to the next safe waiting position on its route. The two new signal types behave a bit differently than standard OpenTTD signal types. This allows 2 trains to be on the same signal block at the same time, so long as they have paths that don't cross. I wanted to use one-way path signals on side tracks to ensure a single direction on them. 2 tracks for both directions and a shared track in between which can be used in both directions for passing slower traffic on 'main tracks'. One-way path signals reserve an individual path between it and the next signal. Description Path signals are the only signals needed by the majority of players, so this PR hides all non-path signals from the signal GUI by default. 1 I'm trying to build a two-way railroad with 3 tracks. I'd like to help you with signals, but I need to understand what you do, and how you reason to "it fails" in more detail than "it does not work".One-way signals reserve a signal block between it and the next signal. There is no way to infer that advice from the first "I cannot add two numbers". A reader can infer from the latter that explaining about 10 and 11 may be useful here. The former gives the reader no clue what happens when I add numbers, in the latter I say not understanding how to go beyond single digits. It's the difference between "I cannot add two numbers" (similar to what you say above) and "I cannot add 3 and 8, since I have no other digits beyond 9 when writing 3+8" (a concrete case with a reasoning what fails). I ask this, because "it does not work" gives me no clues what is happening. Please tell us concretely what you do (up to the point that anyone can replay it, eg "open signal gui click this and this button, move to there, do left-click, program crashes."), what the program does, and how that is wrong in your eyes. What happens if you try to build a 2-way path signal (picture?!) Neither multiple clicks, ctl, shift, nor alt allow me to put one down.I don't understand this.
